6 to v8 swap

[ezz16]

I would like to introduce myself. sort of. I've been on the board a while in the 47-59 forum. Barry (59yo) and my son Max (17) from NC.
my son bought him a 66 c10 because he wanted something different than the ol man. no problem with that but will jump to the question

66 c10, 292 6cyl 3 on tree. have bought a 350 and had Muncie 4sp laying around. so going to swap it. but want to know what some of you have done and if you would do it different?

I have a set of v8 motor mount brackets for the frame and i think the 292 bell housing will bolt to the 350 so can I put a flywheel/clutch kit on the 350 and just bolt it in with the different motor mount holes in the frame? will the hei distributor clear the firewall? and then just swap the trans?

and then there is the frame mounts that move the motor forward and a bolt in trans cross member that does away with the bellhousing mounts. and then I will have to go with a different 1 piece driveshaft am I correct on these 2 different approaches?

This is a budget build keep that in mind thank's for advice
